Just after some advise folks have plenum off goin to do a plenum bypass does it matter if i dont drill out the attachments under plenum by throttle bodies just a thought as in tt.net thread advises to do so.

 

Thanks

Any chance you can expain a bit better? All you need to do is re-route the coolant lines.....

no doesnt matter, you can just leave the metal water pipes on the throttle bodies, it just makes it look a bit more tidy

Yer didnt think so thanks 4 that will leave em on.

keep seeing this bypass on threads. In laymans terms what does it do?

due to the lack of remove around the engine, heat is a concern especially after 15years+ the routing of the water feeds carry under the plenum to aid cooling, in the UK its not so important to have this due to temps compared to japan/australia/us

 

and more importantly the feeds carry to the turbo's what can happen is un-suspected water leaks (pinholes in the aged hoses which left unattended could cause overheating.

 

plenum bypass re routes the coolant feeds so the pass directly from the main water pipes which lead to the heater matrix and splice off direct to the both turbos, so in turn any leaks dwn the line are easier to notice/remedy.

ahh haaa

So you block of the feed and redirect it strait to the tubs. ok with ya.

you dont need to block anything bud, its a case of snipping the hoses coming out from under the plenum so NO coolant passes around under the plenum, these are then redundant, you then fit the hoses in a way they go to the turbos only rather than a puzzled direction.
